God wishes to let himself be found by those who seek him. Hence he wishes first to be sought. So we can see why natural revelation is not absolutely clear and unambiguous but is rather an incentive to seek. Supernatural revelation answers the questions raised by natural revelation. Faith is already a finding and corresponds to God letting-himself-be-found, not only in the sense that he has something said about himself through his word but that through his word he himself has himself found.
Faith is a gift that must be accepted. In faith divine and human freedom meet. But it is a gift that bids us ask for more. As dark and lacking the evidence of insight [uneinsichtig], faith awakens a yearning for unveiled clarity; as mediated encounter, it awakens a longing for an immediate encounter with God. Indeed the very content of faith awakens desire by promising the beatific vision.
